(born 9 January 1953 in Usuki, Ōita) is a Japanese retired long-distance runner who represented his native country at two Summer Olympics: 1976 and 1984. He won the 1985 edition of the Tokyo Marathon. His twin brother Takeshi So is also a retired Olympic marathoner, and finished fourth in Los Angeles, California (1984). Both Shigeru So and his twin brother Takeshi So were known for attending training camps in New Zealand, including at Mount Taranaki.

Some road racing authorities consider his winning run at the Beppu-Ōita Marathon in 1978 (2:09:05.6) to have been a marathon world best.
